Tanith, I understand you feeling upset, three months is no time at all following bereavement, especially the one you experienced (are experiencing)
I can only think of two close friends who took their husband's names on marriage, the rest of us kept our birth name. I know several couples who chose a new name, or made one by combining pieces of their own birth names. Friends in other countries where the tradition is not for women to give up their name and take their husbands, are always shocked by our tradition. I'm surprised that some people continue to find it a surprise when women remain a Ms birth name.
Ms has nothing to do with being widowed or divorced, its a choice that means women's marital/other status isn't announced as soon as they give their name.
